refactor: Standardize @include reference system across all command files

- Fix @include references to use underscore format (Universal_Legend, Standard_Messages_Templates)
- Add missing ultracompressed.yml shared pattern file
- Update broken reference paths in all 18 command files
- Ensure consistent template naming across command system
- Optimize command file structure with standardized includes
